Abstract

An output system (186) for a fluidic angular rate sensor (74, 314) or other device having two fluid pressure outputs is used to convert the dual outlet pressure signals to a pair of oscillating electrical signals whose relative frequency differential is very accurately indicative of the outlet pressure differential of the sensor or other device. The dual outlets of the sensor or other device are fluidically coupled to the control ports of the first amplifier (256) in a cascaded series of fluidic proportional amplifiers (256, 258, 260). The outlet ports of the terminal amplifier (260) are coupled to the inlet ports of a pair of fluidic oscillators (262, 264). A pair of microphone type-pressure-to-electric transducers (266, 268) are driven by the oscillators to produce the oscillating electrical signals. The system is applicable in the field of navigational guidance systems (10) for deriving pulsed electrical angular rate signals representing rotations about up to three control axes utilising fluidic angular rate sensors (74, 314) in place of conventional mechanical rate gyroscopes.
